How cool is this trinket box made from a vintage Texas Instruments calculator?
It's the perfect place to hide your usb stick, the key to your secret diary or even your safe key!
Features a felt-lined hiding space in the main body, and another in the former battery compartment on the back.
This Texas Instruments hand-held electronic calculator with non-working LED display dates from about 1973 and was one of TI's first ever calculators! More info on this calculator here.
Would make a unique gift for a math geek! Only one available.
Size: 16 x 8 x 4 cm
